Satellite Map

Why we love it

When a detailed and fascinating dataset is brought to life, the result is uniquely compelling. At first sight, this map simply shows the current location of approximately 1,250 satellites. As you explore the map, its design gives clarity to what seemed like an unorganised pattern. We love that when you click on a satellite you see its path of orbit and 24-hour trajectory shadow.

Why it works

To plot orbiting satellites and paths on a flat, static map would create quite a mess. A virtual globe allows us to plot satellites along with their height for a realistic impression. We see satellites in a fixed position, colour-coded by type. You can zoom and pan, and watch satellites move around the screen as you move the globe. Click a satellite for specific details, list them and toggle different types on or off.

Building the app

Requirements

Data and software

Any objects or phenomena that have some spatial component are ripe for mapping but it’s important to develop a cartographic approach that suits the thing you’re mapping. Software used: ArcGIS API for JavaScript.

Analysis

The most important processing step: ensure correct horizontal and vertical geometry are calculated based on the satellite TLE Data.

Time

Sourcing and processing the data takes a few hours. The main time was in the construction of the highly customised app using the JavaScript API. It took a couple of days to configure it to support a clean, immersive experience.

Tips and tricks

Choose colours and symbols wisely

Simple symbology and strong, highly saturated colours work well for web browsers and the black background evokes the impression of outer space in this map.

Keep it simple

An intuitive user interface of a web map or app creates an experience where users can immediately engage.
